Description
Technical field
The utility model belongs to unmanned machine inspection technical field, is related to a kind of unmanned inspection monitoring of thermoelectricity water system equipment
Device.
Background technology
With flourishing for thermal power generation, the development of thermoelectricity technology is also maked rapid progress.But Thermal Power Generation Industry fast development
Some no small drawbacks are also slowly embodied simultaneously, such as high-tech talent development speed in terms of thermoelectricity and quantity are much
Backwardness thermoelectricity development.Water system as one more special part of thermal power plant, technological process and technology completely into
It is ripe, but in terms of equipment routing inspection or will by it is original it is artificial be detected, not only to expend many manpowers, efficiency is not yet
It is high.
1) manual inspection
Can with the development of DCS system function and Fieldbus Intelligent equipment, operating personnel in current thermal power plant
Enough various equipment operational factors (such as temperature, pressure, flow etc.) are introduced in control system logic to carry out equipment running status
Monitoring, and the degree operated without people's real time inspection can be reached by strategy design, this causes labor workload to greatly reduce, but
Field apparatus " run, drip, leak " problem still needs manually to carry out checking detection to scene.
The equipment routing inspection of thermal power plant is mainly carried out by artificial " soon, hand is touched, ear is listened " at present, and water system is relative
Come with host computer system, require all to compare " low " in device security, equipment detection.Therefore to equipment in equipment routing inspection work
Testing requirements nor very it is careful：
A) situations such as being primarily upon " run, drip, leak " with detection device.I.e. water system inspection is most importantly paid close attention to
Whether have whether situations such as situation and whether complete device outer surface of " run, drip, leak " (has crack, is stained with inspection equipment
Deng).
B) " not high " is required to the vibratility of equipment.Equipment is mainly pump, pitch, osmosis filtration device and inspection in water system
